Great – VR World for Google Cardboard Review

I'm writing this review on behalf of my 6 year old who recently discovered Google Cardboard. This is his favorite app to date. Overall, this is a great app. The one thing keeping it from 5 stars, in his words - "I want to get to climb the mountain past the big hole. Thank you." I don't know exactly what he is referring to, but he did show me a big mountain past a canyon that you can't seem you can navigate to. And, well, he would like to climb up it and continue exploring. I promised I'd relay this feedback... he actually wrote a letter, but, well, hopefully this will suffice. Overall great app, works really nicely on the Google Cardboard viewer.
